Efficacy of intra-operative adductor canal block in total knee arthroplasty: a prospective observational study
Abstract
Background: Effective postoperative pain control after total knee arthroplasty (TKA) remains a clinical challenge. This study aimed to evaluate the efficacy of intraoperative adductor canal block (ACB) in providing pain relief and preserving quadriceps function. Methods: This prospective observational study included 92 patients undergoing primary TKA. Intraoperative ACB was administered by the operative surgeon, and outcomes assessed included pain scores (visual analogue score (VAS) at multiple time points), quadriceps muscle power, complications, and postoperative analgesic use. Statistical associations were evaluated using Chi-square and t-tests with p
